Figure Caption
Example invariant-mass distribution for the K*± in pp collisions at 13 TeV in the pT range 1.2 < pT < 1.4 GeV/c. The figure shows the invariant-mass distribution after subtraction of the mixed-event background (plotted with statistical uncertainties) with a fit to describe the peak of the K*± (solid curve) and the residual background (dashed curve).
Detail description
Data sample: LHC15f, pass2, ESDs
Event selection: Physics Selection, |vz|<10 cm, other standard event-selection cuts for PWG-LF 13-TeV analyses (see analysis note)
Track Cuts: standard ITS/TPC track cuts 2011 (see analysis note)
V0 Selection: Standard K0S selection except for pT depedent DCA of tracks to PV, and Mass tolerance instead of Competing V0 Rejection
